Hi All,

Before I get go and try to work out a work around for this issue I thought I would see if I am doing something very wrong which is causing the problem. Sorry if this is stupidly simple....

Okay, firstly I have used ModelAdmin to create a product list (this is just an online catalogue not e-commerce). I have create a page type called ProductDetails.php

<?php

/**
 * Application Aggregator to display the list of Markets in the system
 */

class ProductDetails extends Page {
	
}

class ProductDetails_Controller extends Page_Controller {
	public static $allowed_actions = array (
		'show'
	);
	function ProductDetails() {
		$where = Convert::raw2SQL(Director::urlParam('ID')); 
		$whereStatement = "ID = '". $where ."'"; 

		return DataObject::get("Product", $whereStatement);
	}
	function ImageExists() {
		// Check that the image file exists for this page 
		// in the specified path 
		$filename = 'assets/Uploads/products/product-$ItemId-1.png';
		if(Director::fileExists($filename) == true) {
			return true;
		}else{
			return false;
		}
	}
}

So the ImageExists() function should check if the particular image is on the file system and if it is it should display the image using an if statement in the template

<% if ImageExists %><img src="assets/Uploads/products/product-$ItemId-1.png" alt="$Title" /><% end_if %>

Now the problem is that this needs to exist inside the <% control ProductDetails %> object. Everytime I test this nothing work. I have even tried just returning a string and outputting that directly within this controller. If I put the <% if ImageExists %> outside the Product Details controller then it shows up fine...

Below is my full template. If you have any suggestions of what I should be trying I would be truly grateful. It has had me puzzled for the last couple of days.

Kind Regards,
Colin

Its because as soon as you go into that <% control ProductDetails %> the scope the the template changes to the 'Product' object. To call that ImageExists method you either need to move it from the ProductDetails_Controller to the Product class or you could try doing <% if Top.ImageExists %> in the control - the Top goes back up to the top most level.

Thanks Willr,

I'll give those two things and try and update the post once tested.

Cheers,
Colin
